[UPDATE Donald Trump’s team is denying reports that the transition is selling multi-day hunting or fishing trips with the president-elect’s eldest sons as part of an inauguration weekend party.

“The Opening Day event and details that have been reported are merely initial concepts that have not been approved or pursued by the Trump family,” spokeswoman Hope Hicks said in a statement. “Donald Trump Jr. and Eric Trump are avid outdoorsmen and supporters of conservation efforts, which align with the goals of this event, however they are not involved in any capacity.”]

Hunting enthusiasts Donald Jr. and Eric Trump will be ringing in their father’s ascent to power with a fundraiser and bash dubbed “Opening Day 2017,” according to an invitation obtained by TMZ and reported on Monday.

“Camouflage & Cufflinks” is the preferred attire at the event, to be held one day after the inauguration at the Walter E. Washington Convention Center in downtown Washington, D.C.. Entertainment will be provided by country music favorites Toby Keith and Alabama.

“Opening Day is your opportunity to play a significant role as our family commemorates the inauguration of our father, friend and President Donald J. Trump,” the invite reads. “Join us as we celebrate the great American tradition of outdoor sporting, shooting, fishing, and conservation.”

However, the significance of that “opportunity” varies: A “Wild Turkey” donation of $25,000 is enough to net 6 tickets (including 2 VIP access) to the event, but only the biggest trophies—”Grizzly Bear” ($500,00) or “Bald Eagle” ($1 million)—are enough to secure a “[m]ulti-day hunting and/or fishing excursion for 4 guests with Donald Trump, Jr. and/or Eric Trump, and team.”

The fundraiser was leaked days after a New York Times report on a “Coffee with Ivanka” auction exposed another effort by the Trump children to capitalize on their proximity to the White House.

According to TMZ‘s “sources,” the event is “legit,” though it remains unclear if the President-elect will attend. The party is supposedly “being thrown to thank the hunting, shooting, and fishing communities for their support,” TMZ notes. The invitation states that net proceeds will be donated to “conservation charities.”

Both Donald Jr. and Eric have come under fire for hunting exotic animals and rare species. What’s more, the sons are credited with having significantly “influenced the president-elect’s thinking on conservation issues,” The Hillreported Monday, pointing to the recent selection of Rep. Ryan Zinke (R-Mont.) to lead the Interior Department.

Donald Jr. had reportedly “hit it off” with Zinke, another “avid outdoorsman,” who supports preserving—and drilling on—public lands. Also, according to Kierán Suckling, executive director of the Center for Biological Diversity, Zinke has “voted for legislation to remove grizzly bears from the endangered species list, wolves, lynx, he’s fought protection for the sage grouse, and at every turn and he wanted to exempt big water developers…in California from the Endangered Species Act.”
